PRT CTRL Integrated Controller Reference Manual

The RTHP (Roof Top Heat Pump / Roof Top Heat Pack) programmable function allows the
direct control of multiple stage Roof Top Heat Pumps used for large retail or commercial space
temperature control. There is a substantial number of configuration screens for the RTHP unit
and a working knowledge of Air Conditioning and Temperature Set Point configuration is
essential in setting up the correct operation of the programmable function.
FN001 Func Type
RTHP Control
Use the [1] and [3] keys to scroll the function types until you reach the RTHP control
selection and press [ENTER] to select the function type displayed and proceed to the next
programmable option for the RTHP control function. For more information about the list
control data entry refer to the section List Control Data Entry on Page 406.
Function Mode
The function mode determines how this function operates with the system controller. By
default a function is set to normal operation. Normal operation will mean the function is
started if it was running when the system restarts or is completely powered down (AC Failure
and Battery Failure). The Run Once mode of operation will allow the function to run once and
then wait to be stopped and started by the user or operator. Setting the run once option for
the RTHP will result in NO operation being performed and the function stopping a short time
after it is started.
FN001 Func Mode
Normal
Use the [1] and [3] keys to scroll the function mode until you reach the normal selection and
press [ENTER] to proceed to the next programmable option for the RTHP control function.
For more information about the list control data entry refer to the section List Control Data
Entry on Page 406.
Enabled Control PGM
Enabled Control PGM is set when the RTHP is to run and will operate only when the enabled
PGM is on. If no enabled PGM is set the RTHP will run continuously. This allows the RTHP to
operate only during the times that the space is occupied. The signal can also be a memory
register or a Boolean (bit) value from the selected memory register.
FN001 Enabled
pgm: --000:00
To modify the occupy PGM, use the settings as explained in section Entering PGM and PGM
Groups on Page 410.
Fault PGM
The fault control PGM is set when a fault condition has occurred and the RTHP is to shutdown.
This allows the RTHP to shutdown in the shortest possible time without causing any damage
to the system. In the case of a fire shutdown the system must have a fire PGM programmed.
